The plug has a nipple 42 extending from the bottom over which a chain 43 is secured, and said chain 43 has a large ring 44 which is larger than the opening 37, and thereby adapted to retain the plug 40 in a suspended position ready for replacing whenever it is removed from the cap 8in o-rder to fill the oil reservoir 3. Av strainer of usual construction is mounted in the oil reservoir 3 to prevent any dirt or foreign substance from going through the valves into the mechanism to be lubricatedv from the oil reservoir 3.

' The oil reservoir 3 is filled withl oil by removing the plug 40 from the cap 8 and replacing the same in the threaded boring 39. Y The oil will pass through the boring 16, and Iby the needle valve 14 into the vnarrow passage 17, and thence into the upper valve chamber 23 which is opened when the air pump to which this lubricator is adapted to be secured is on the pressure stroke. This permits the oil to pass through the tubular opening 25 into the lower chamber 24. The positions of valves 30` and 31 during this operation are shown'in Figure 1'." While the valve 30 is on its upward movement as described a slight amount of air will pass by this valve and through the passages 25, 23, 17, 16, 46, 19, and 18 to the top of the oil reservoir, creating a( slight pressure and preventing a formation of a partial vacuum which may interfere with the vsteady and regular. operation ot the device. While the valve 31 is thus held on its seat 28 a certain amount of oil is permitted by the position of the needle valve 14 to trickle down through the narrow opening 17 linto the upper chamber 23, thence through the tubular opening 25 into the lower chamber 24.' When the piston of the air pump reverses the motion and 'is on the suction stroke the Valve 31 drops away from its seat 28 and the valve 3() closes.
